Purpose: In a strict sense epibulbar dermoids are defined as congenital changes of mesodermal and ektodermal origin. Usually they are located at the limbus of the cornea in the inferotemporal quadrant, rarely they can be observed in more central regions of cornea. Intraocular structures are rarerly involved. Connections to Goldenhar`s oculo-auriculo-syndrome exist. Because of cosmetical reasons or a considerable astigmatism holding the danger of amblyopia a resection might be necessary.
Method: Six patients (three girls and three boys) at an age from 9 month to 8 years with limbal dermoids where included in the present study. All patients consulted the university eye hospital of Dresden for a possible therapy.
Results: All children showed a unilateral dermoid in the inferotemporal quadrant. In five cases the left eye was affected. In two patients a goldenhar syndrome was present.
In two patients a local resection of the dermoid was indicated.
In three patients a keratoplasty (two lamellar, one penetrating) was carried out additionally. In one case of a two year old girl only a prophylaxis of amblyopia was considered.
The postoperative results reached from uncomplicated healing (visual acuity 1,0) to full cloudiness of the transplantat and re-keratoplasty (visual acuity lux).
Conclusions: Controls of the dermoid in half-year-intervals and surgical intervention in early childhood sho
